We are Dementia UK, the specialist dementia nurse charity.

Our nurses, called Admiral Nurses, who we continually support and develop, provide life-changing care for families affected by all forms of dementia - including Alzheimer's disease. When you support our charity, you're helping us grow the number of specialist dementia nurses, giving more people affected by dementia the life-changing care that they need.

We help people living with dementia stay independent for longer and support the people caring for them. We help to give them the strength to cope with the bad days, and the energy to enjoy the good days.

With your help, no one will face dementia alone.
